W. R. CARMICHAEL ENVELOPE CONSTRUCTION Filed Dec. 3, 1957 F/gt/ June 6, 1961 United States Patent 2,987,327 ENVELOPE CONSTRUCTION Walter R. Carmichael, 1736 White Ave., Knoxville 16, Tenn. Filed Dec. 3, 1957, Ser. No. 700,448 3 Claims. (Cl. 282-25) The present invention generally relates to novel concepts in the construction of an envelope incorporating features which enables the message receiving member to be preincluded in the envelope together with impression transferring material interiorly of the envelope and a flap or panel exteriorly of the envelope whereby the message may be typed upon the exterior flap or panel with the impression being transmitted to the message receiving member without appearing on the outside of the envelope thus eliminating the necessity of first typing the message on the message receiving member and then folding the same and placing it in the envelope and generally forming a highly efiicient and elfective envelope construction.

The primarypurpose of the envelope and enclosure is to save time and money in routine mailing procedures by elimination of certain steps normally employed in correspondence. The device eliminates many motions now necessary in preparing a letter for mailing such as the insertion of the letter form on which the message is to be typed into the typewriter, taking it out and folding and inserting the same in the envelope after the envelope has also been inserted in the typewriter for addressing. After the letter form has been inserted in the envelope, the same must be sealed. In instances Where a relatively large volume of correspondence is to be mailed, this job is exceedingly time consuming and tedious. With the present invention, it is only necessary to insert the envelope with the preincluded letter form therein into the typewriter with it only being necessary to type the addresses and the messages during one operation after which the sealed envelope may be removed and the exterior panel or flap may be removed thus providing the envelope in a condition for mailing with the exterior panel or flap being possibly employed as a record of the correspondence.

Other objects of the present invention will reside in its simplicity of construction, ease of assembly, efliciency in use and its relatively inexpensive manufacturing cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in Which;

FIGURE 1 is a plan view of the blank from which the envelope of the present invention is formed;

FIGURE 2 is a plan view of the envelope in condition for use;

FIGURE 3 is a plan view of the envelope ready for mailing after the front flap has been removed therefrom;

FIGURE 4 is a longitudinal, vertical sectional view taken substantially upon a plane passing along section line 4-4 of FIGURE 2 illustrating the details of construction thereof;

FIGURE 5 is a detailed sectional view taken substantially upon a plane passing along section line 5-5 of FIGURE 3 illustrating the construction of the envelope when mailed;

FIGURE 6 is a perspective view of the preincluded letter form which may be inserted into the envelope prior to scaling thereof; and

FIGURE 7 is a perspective view of the tear-off flap Patented June 6, 1961 disposed in overlying relation to a portion of the front panel of the envelope.

Referring now specifically to the drawings, the numeral 10 generally designates the envelope construction of the present invention which includes a back panel 12, a front panel 14 secured to the back panel 12 along a longitudinal fold line 16. The top edge of the front panel 14 is provided with a top closure flap 18 while the end edges of the front panel 14 are provided with end closure flaps 20. One end of the back panel 12 is provided with a flap or panel 22 secured to the back panel 12 by virtue of a transverse perforated line 24 and fold line 23.

The front surface of the front panel 14 is provided with indicia 26 indicating the addrwsee and addressor of the envelope and is also provided with a stamp receiving area 28 with the stamp receiving area 28 being disposed adjacent the upper right hand or conventional area of the envelope while the indicia '26 are located adjacent the left hand side of the envelope.

Impression transferring material 30 is disposed on the inner surface of the front panel 14 in facing relation to a message receiving letter form 32 whereby impressions made on the outer surface of the front panel 14 will be transferred to the letter form 32 which may be either a folded letter form or any other type of letter form normally employed. The outer surface of the flap 22 may be provided with guide lines 34 which are orientated in relation to guide lines 36 on the letter form 32 whereby material may be written on the flap 22 in a predetermined area whereby the impressions will be transmitted to the same predetermined area on the letter form 32.

When the blank shown in FIGURE 1 is assembled into the condition shown in FIGURE 2, the preincluded letter form is disposed therein and the envelope is sealed by virtue of the end closure flap 20 and the top closure flap 18 being adhesively secured to the rear panel 12. The flap 22 is folded around the end of the envelope into overlying relation to the front surface of the front panel 14 and covers a portion thereof for forming an area upon which a message may be either hand written, typewritten or formed thereon by any other suitable means. Adjacent the free edge of the flap 22, the name and address of the sender as well as the person for whom the envelope is intended may be imprinted by the same message writting or forming implement. The coating on the inner surface of the front panel will transfer the impression from the flap 22 to the preincluded letter form without transferring any impression to the outside of the envelope after which the envelope may be readied for mailing by simply removing the flap 22 along the perforated line 24 tucking in the remainder of the right hand edge of panel 12 and folding right hand flap 20 around the end of the envelope and sealing the flap 20. The coating 30 may be in the form of an inserted piece of carbon paper, a carbon coating on the inner surface of the front panel or a chemical coating that may be coated all over or in spots which also can be done with carbon coating. In fact, any type of material which will transfer an impression from the front panel to the preincluded letter form is acceptable and could be of the type which will transfer only a single message since the envelope would not normally be reused.

While only one specific embodiment of the invention has been illustrated and described, it is pointed out that various modifications and forms of the invention may be employed without departing from the purview thereof. As an example, a double flap may be provided for providing yet another extra copy of the message which may be retained by the sender for his records. Of course, any type of envelope panels may be employed such as the well known window envelopes and it is also within the purview of the invention to have the exterior flap disposed on the rear of the envelope with the flap being normally secured to a portion of the'envelope by virtue of aperfor-ated line.

The foregoing is considered as illustrative only of the principles of the invention.
